IMHO... Purely a sales gadget..

The 4x6 printers are generally not worth the high cost of consumables.
Print quality will be no better than WalMart. In fact, you can
typically get the same quality from your existing inkjet printer as
you can from your "super-doooper" 4x6 printer.

The only reason to get one of these is if you have a real need to get
instant prints (as you watch them slooowly come out)... otherwise the
coolness of a 4x6 printer will quickly wear off and you'll have an
expensive paperwieght on your desk.

I'm going to ebay mine (K*dak) as soon as it runs out of paper/ink.

If you are still going to get one... go for a dye-sub unit so you
don't have to deal with ink clogs, etc.
